Description

  The present invention relates to a control device, an image processing device, a memory information storage control method, a memory information storage control program, and a storage medium, and more particularly, to a control device that stores memory information in an attachable / detachable storage medium when an error occurs, and an image The present invention relates to a processing device, a memory information storage control method, a memory information storage control program, and a storage medium.

  Conventionally, in a control device that executes an application program on a general-purpose OS (Operating System) such as UNIX (registered trademark), if the operation of the application program cannot be normally continued, the application program is forced from the OS. A function to terminate automatically is implemented. For example, in a general-purpose OS represented by UNIX, when a situation in which the operation of an application program cannot be normally continued occurs, a signal is transmitted to the application program, and the processing of the application program is terminated. Core dump processing is executed depending on the type of signal transmitted to the application program.

  In recent years, built-in image processing apparatuses such as small printers, facsimile machines, copying machines, and multi-function apparatuses that have previously incorporated specific functions are based on UNIX-based general-purpose OSs because of the demand for higher functionality. An OS is adopted, and core dump processing is executed when an abnormality occurs.

  The OS conventionally executes this core dump process as shown in FIG. In other words, when a failure set to execute the core dump process occurs, the OS calls the core dump execution unit, and the core dump execution unit first creates the name of the core file as shown in FIG. 13 (step S1001). ). This core file name is created using the name of the application program that caused the failure, the process ID, and the like. Next, the core dump execution unit checks whether a file with the core file name can be created in the working directory of the application program to be dumped (step S1002). End core dump processing.

  In step S1002, when a file with a core file name can be created in the working directory, the core dump execution unit creates a file with the core file name (step S1003), and stores the memory information used by the application program in the OS. Is written in the file with the size of the memory block managed by the server (step S1004).

  When the memory information is written to the file, the core dump execution unit checks whether the writing is performed normally (step S1005), and when the writing is not performed normally, the core dump process is terminated.

  If the writing is normally performed, the core dump execution unit checks whether the written memory information is the last block in the memory used by the application program (step S1006). If the writing is not the last block, the process proceeds to step S1004. Returning, the memory information used by the program is processed in the same manner as described above from the process of writing the file with the size of the memory block managed by the OS (steps S1004 to S1006).

  In step S1006, if the written memory information is the last block in the memory used by the application program, the core dump execution unit ends the core dump process.

  Such core dump processing is performed by writing memory information to a mass storage device such as a hard disk. However, in a small and inexpensive device such as an embedded device, a mass storage device such as a hard disk is used. In many cases, it is difficult to use the core dump function.

  Conventionally, a technique for generating a core file suitable for a preset storage size before executing a core dump has been proposed (see Patent Document 1).

  Conventionally, a technique for outputting a core file to a remote hard disk device via a network has been proposed (see Patent Document 2).

The registration function unit (registration means) 31 registers the memory information storage location, and the setting file 32 is used by the registration function unit 31 and is a file in which the memory information storage location registered by the user is described in advance. . This setting file 32 may not exist as a file in the removable storage device 30 when the user does not designate a memory information storage location.

  The registration function unit 31 is not limited to being stored in the removable storage device 30. For example, the registration function unit 31 is mounted on the ROM 12 as shown in FIGS. The possible storage device 30 may store a setting file and key information 33.

  The key information 33 is information indicating the removable storage device 30 for storing memory information, and is not necessary when the removable storage device 30 as a storage destination of memory information is not limited. However, as shown in FIGS. 5 and 6, when the registration function unit 31 is mounted on the image processing apparatus 1 instead of the removable storage device 30, the removable storage device stores key information 33. By restricting the storage destination of the memory information only in the storage device 30, the memory information may be prevented from being inadvertently stored in the removable storage device 30 in which the key information 33 is not stored and flowing out.

  As described above, when the power of the image processing apparatus 1 is turned on, the CPU 11 reads the OS 21 from the ROM 12 into the RAM 13, starts execution of the OS 21, and copies the function unit from the ROM 12 according to the configuration of the image processing apparatus 1. 24 and the operation unit control function unit 23 are read and executed on the RAM 13.

  That is, the system program 40 and the application program 50 are arranged on the RAM 13 as shown in FIG. The system program 40 includes an OS 21.

  The application program 50 includes the execution function unit 22, the operation control function unit 23, the copy function unit 24, and the registration function unit 31. The registration function unit 31 exists only when performing registration processing, and is always on the RAM 13. Does not exist.

  Next, the operation of this embodiment will be described. The image processing apparatus 1 according to the present embodiment allows the controller 2 to attach / detach the memory information to / from the removable storage device mounting ports 19a to 19n when a preset situation occurs such as when a problem occurs in the execution of the application. Memory information storage processing to be stored in the detachable mounting device 30 attached to the memory, but prior to the memory information storage processing, name information storage location registration processing for registering the removable storage device 30 as a storage location of the memory information The memory information storage control process is performed.

<Memory information storage location registration process>
First, a memory information storage location registration process for storing memory information in the removable storage device 30 will be described with reference to FIGS.

  When the removable storage device 30 is attached to any of the removable storage device attachment ports 19a to 19n, the removable storage device 30 is attached from the removable storage device attachment ports 19a to 19n, as shown in FIG. This is notified to the execution function unit 22 (step S101). When the execution function unit 22 is notified of the attachment of the removable storage device 30, the execution function unit 22 issues a mount request for the removable storage device 30 to the OS 21.

  The execution function unit 22 issues an execution request to the registration function unit 31. When issuing the execution request, the execution function unit 22 notifies the registration function unit 31 of the location where the attached removable storage device 30 is mounted on the file system of the OS 21 as a storage location (step S104). ).

  Next, as shown in FIG. 9, the registration function unit 31 checks whether or not the setting file 32 exists in the attached removable storage device 30 (step S105). If the setting file 32 does not exist, The location where the removable storage device 30 notified from the execution function unit 22 is mounted is registered as a memory information storage location (core file storage location) using the registration interface 41 provided by the OS 21, and the memory The information storage location registration process is terminated (step S106).

  The registration function unit 31 checks whether or not the key information 33 indicating the removable storage device 30 for storing the memory information exists before confirming the setting file 32 in step S105. It is also possible to check the setting file 32 by determining that the removable storage device 30 is used for storing memory information on the condition that the storage file 30 exists.

  In step S105, when the registration function unit 31 finds the setting file 32 in the removable storage device 30, the registration function unit 31 reads the memory information storage location (core file storage location) described in the setting file 32 from the setting file 32. (Step S107). Next, the execution function unit 22 combines the notified location where the removable storage device 30 is mounted and the memory information storage location (core file storage location) read from the setting file 32, so that the removable storage device is connected. 30 is used to create the name of the memory information storage location (core file storage location), and the name of the created memory information storage location (core file storage location) is registered using the registration interface 41 provided from the OS 21. Register (step S108).

  When the registration interface 41 is used, the OS 21 registers the memory information storage location (core file storage location) passed to the registration interface 41 in the storage location registration list 42 held by the OS 21, as shown in FIG. (Step S109).

  When the registration is completed, the registration function unit 31 checks whether a memory information storage location (core file storage location) that has not been subjected to registration processing is described in the setting file 32 (step S110), and has not performed registration processing. If there is a description of the memory information storage location (core file storage location), the process returns to step S107, and the same processing is performed from the processing of reading the description of the memory information storage location (core file storage location) from the setting file 32 (step S107). S107 to S110).

  The registration function unit 31 repeats the processes of steps S107 to S110 as much as the description of the memory information storage location (core file storage location) in the setting file 32, and performs registration processing in the setting file 32 in step S110. When there is no description of the memory information storage location (core file storage location) that has not been performed, the memory information storage location registration processing is terminated.

  As described above, when the registration interface 41 is used, the OS 21 registers the memory information storage location (core file storage location) passed to the registration interface 41 in the storage location registration list 42 held by the OS 21. However, as shown in FIG. 10, in the storage location registration list 42, when registering the memory information storage location (core file storage location), for example, the addresses are assigned in ascending order of registration requests using the registration interface 41. When the memory information is stored in order (from the top in FIG. 10), the storage location is selected in the reverse order of the memory information storage location registration.

<Memory information saving process>
Next, a memory information storing process for storing memory information will be described with reference to FIGS.

  When a malfunction that has been set in advance to execute the memory information storage process (core dump process) occurs in the application program 50 being executed, the OS 21 calls the core dump function unit 43 as shown in FIG. First, the name of the memory information file (core file) to be created is created (step S201). The core dump function unit 43 performs the creation of the memory information file name (core file name) by using the name of the application program that caused the failure, the process ID, and the like.

  Next, the core dump function unit 43 checks whether or not a memory information storage location (core file storage location) is set (step S202), and when it is set, “1” is calculated from the number of registered memory information storage locations. Is stored in the variable m (step S203), and a storage name of the memory information file (core file) is created from the variable m and the memory information file name (core file name). In this case, the core dump function unit 43 creates a save file name including the save location from the memory information file name (core file name) created in step S201 and the save location registration list 42 (step S204). As described above, the method for selecting the storage location from the storage location list 42 is performed in the reverse order of the registration of the storage location. That is, the registration location to be used is selected from the storage location registration list 42 from the storage location registered last to the storage location registered first.

  Next, the core dump function unit 43 tries to create the memory information file (core file name) including the storage location, that is, the memory information file (core file) with the absolute path designation core file name. It is checked whether the memory information file can be created (step S205). If the memory information file can be created, the memory information file (core file) is created at the storage location as the storage location. It is checked whether there is a free area in which a (core file) can be created (step S206).

  When it is not possible to create a file with an absolute path designation core file name in step S205, or if there is no free area in which the memory information file can be created in step S206, the core dump function unit 43 performs processing as shown in FIG. Is checked whether a memory information storage location (core file storage location) that has not yet been checked is registered (step S207). If there is an unchecked memory information storage location (core file storage location), the variable m is changed to “ The value obtained by subtracting “1” is set in the variable m (step S208), the process returns to step S204, and the same processing is performed using the variable (steps S204 to S208).

  Then, in step S207, the unchecked memory information storage location (core file storage location) cannot be created with the absolute path designation core file name, or there is no free space where the memory information file can be created in the creation location. When there is no more, the core dump function unit 43 determines that the memory information cannot be saved, and ends the memory information saving process (core dump process).

  In step S206, when there is a free area in which the memory information file can be created at the creation location, the core dump function unit 43 uses the memory information used by the application program in which the above-described problem occurs to the size of the memory block managed by the OS 21. The memory information file file thus created is written (step S209), and it is checked whether the writing has been performed normally (step S210).

  If the writing is not normally performed in step S210, the core dump function unit 43 determines that the memory information cannot be stored, and ends the memory information storage process (core dump process).

  When the writing is normally performed in step S210, the core dump function unit 43 checks whether the written memory information is the last block in the memory used by the program (step S211), and the last block If not, the process returns to step S209 to perform the same processing from the writing of the memory information (steps S209 to S211).

  In step S211, when the written memory information is the last block in the memory used by the program, the core dump processing function unit 43 determines that the memory information storage has been completed normally until the end, and the memory information Save processing (core dump processing) is terminated.

  When the memory information storage location (core file storage location) is not set in step S202, the core dump function unit 43 can create a file with a storage name in the work directory of the application program that is the target of the memory information storage processing. (Step S212), and if the file can be created, the process proceeds to step S209, and from the process of writing the memory information to the memory information file in the size of the memory block managed by the OS 21, as described above. The same processing is performed (steps S209 to S211).

  In step S212, when a file with a storage name cannot be created in the working directory of the application program, the core dump function unit 43 determines that the memory information cannot be stored and ends the memory information storage process (core dump process). To do.

  As described above, the image processing apparatus 1 according to the present embodiment performs the memory information storing process for generating the memory information related to the application program 50 being executed on the memory and storing the memory information in the removable storage device 30 that is a removable storage device. When it is confirmed that the removable storage device 30 is connected, the removable storage device 30 is registered as a storage location of the memory information generated by the memory storage processing.

  Therefore, the memory information can be stored in the removable storage device 30 inexpensively and reliably without limiting the amount of memory information to be stored and without requiring a network connection, and it is necessary to analyze a problem that occurs. Time can be reduced and the usability of the image processing apparatus 1 can be improved at low cost.
